Title: Improvements in hydraulic brake operating mechanisms for vehicles
IPC: B60T11/24
Filed: 1929-12-04
Abstract: 342,063. Fluid pressure brakes. FIAT SOC. ANON., 250, Via Nizza, Turin, Italy. Dec. 4, 1929, No. 37178. Convention date, Oct. 11. [Class 103 (i).] A hydraulic brake for vehicles comprises separate hydraulic systems for the front and rear brakes respectively, and a mechanical equalizing device interposed between the common operating pedal 12 and the two pressure pistons. As shown in Fig. 1, the pressure pistons 3,4 for the front and rear brake systems 5, 6 are coupled to a lever 11 rigid with the pedal lever 12 and provided with a slot through which passes the pivot 14 whereby the pressure applied to the two pistons is equalized. Should one of the systems be damaged and the pressure fail therein, the pivot 14 abuts against the end of the slot so that pressure is still applied to the other system, the driver being made aware of the defect by the increased stroke of the pedal. In another arrangement, the pistons comprise oscillating vanes, connected by links to the ends of a lever which floats by reason of its pivotal mounting upon a swing arm which is connected by a link to the pedal lever. Stops are provided to ensure the operation of the one system in the event of failure of the other. Figs. 3 and 4 show an equalizing mechanism in the form of a differential gear. The carrier 40 of the planet pinion 38 is rigid with the pedal lever 12 and this pinion engages sun pinions 37, 39. The pinion 39 carries an arm 32 connected to one of the pressure pistons 4 and the pinion 37 is formed on a gear wheel 36 engaging a gear wheel 35 which carries an arm 31 connected to the other piston 3.

Title: Improvements in or relating to fuel burners
IPC: F23D11/00
Filed: 1954-12-28
Abstract: 826,665. Burners. SCHIELDROP, B. H. Dec. 21, 1955 [Dec. 28, 1954], No. 37478/54. Class 75(1) A burner comprises a first axially movable valve member 5 for controlling the flow of air through the burner outlet 3, a second axially movable valve member 21 for controlling the supply of fuel to the burner, a single control handle 29 for moving the two valve members together, means for adjusting the amount of movement of one valve member relative to the other and means for adjusting the setting of one valve member relative to the other. The valve member 5 slides on a fixed tube 6 towards and away from the burner outlet 3 and is actuated by a link 31 pivoted to a crank 30 secured to a shaft 28 adapted to be rotated by the control handle 29. The second valve member 21 comprises a rod adapted to slide axially in an end bore 20 in a tubular member 18 threaded into a casing 13. A frusto-conical end of the valve member 21 seats against a shoulder 16 on the casing 13 to form therein an oil inlet chamber 14 and an oil outlet chamber 15. The oil passes from the inlet ,chamber through apertures 19 into the tubular member 18 and then through a V-shaped groove 23 in the valve rod 21 to the outlet chamber from which it is conveyed by a pipe 10 to an atomizing nozzle 11. The rear end of the valve rod 21 is connected by a link 24 to an operating stem 25 slidably mounted in guides 26, 27 formed on the outside of the casing 13. A link 34 is pivoted at one end to a clamp 36 adjustably secured to the operating stem 25 and at the other end to a bolt 35 secured in a slot 33 of a second crank 32 on the shaft 28. Adjustment of the position of the bolt 35 in the slot 33 varies the stroke of the valve rod 21. Adjustment of the clamp 36 on the operating stem 25 enables a different part of the groove 23 of the valve rod to be effective in controlling the oil. In a modified construction for use with a gas burner the valve rod 21 is replaced by a hollow cylindrical member having a rectangular slot in its periphery communicating with an inlet chamber through an aperture. By rotating the slotted member the width of the portion of the slot communicating with the aperture can be varied and the stroke of the slotted member can be varied in the same manner as described in connection with the oil valve. Specification 780,961 is referred to.

The packets 12 and 16 each comprise a blister 32, 18 having encircling flanges to which are sealed closure members 34, 24 closure member 34 being longer than the flange to form an opening tab 36 and one edge of closure member 24 being unsealed to facilitate opening. The sterilizing gas, which may be a mixture of about 12% ethylene oxide and 88% of an inert gas such as carbon dioxide or freon (R.T.M.), is introduced into the packet 12 containing the object 14 by tack sealing the closure member 34 to the blister 32 and subjecting this to a vacuum and then to the sterilizing gas at between atmospheric and 1 PSIG pressure when the heat seal is completed. This process is repeated for the packet 16 in which the packet 12 is disposed in an upside down position. The blisters 32, 18 are preferably of a transparent plastics material and the closure members 34, 24 of metallic foil having a layer of thermoplastics material.

Abstract: 950,590. Winding and reeling. DAVY & UNITED ENGINEERING CO. Ltd. Nov. 1, 1960 [Nov. 5, 1959], No. 37634/59. Heading B3E. Apparatus for coiling strip comprises a rotatable mandrel on which the coil is wound, a plurality of wrapper rolls distributed around the mandrel so as to run on the periphery of the coil when the mandrel is rotated, gas pressure means for maintaining pressure between the wrapper rolls and said coil when the rolls are running thereon, and liquid pressure means for moving the rolls rapidly away from the coil. Hot steel strip is fed to a rotated expandable mandrel 1 by pinch rolls 28 through guides defined by fixed plates 11, 12, 13, a roller 14, a plate 15 pivoted about the axis of the roller 14, and a plate 10 carried by an arm 5 on a spindle 6d. The first few turns are urged and guided on the mandrel 1 by rotated wrapper rolls 2a, 2b, 2c, 2d journalled in pairs of arms 5 also carrying deflector plates 9a, 9b, 9c and 9d. The pairs of arms 5 are mounted on spindles 6a, 6b, 6c, 6d, the latter three being connected by arms 21 (not shown) and 22 to piston rods 20x (not shown) and 20y of doubleacting air piston and cylinder assemblies 16 and a single-acting hydraulic piston and cylinder assembly 17. The spindle 6a is connected by arms 26 to the piston rods 25 of double-acting air and oil piston and cylinder assemblies 23 pivoted about fixed axes 24. Alternatively, an air cylinder could act on one of the arms 26 and an oil cylinder on the other arm 26. As the coil on the mandrel 1 expands the rolls 2a, 2b, 2c and 2d are forced radially outwards against air pressure in the cylinders 16 and 23, which pressure may be maintained constant. When the coil has grown to a predetermined size the rolls are withdrawn rapidly by admitting oil under pressure to the cylinders 17 and 23 which movement is assisted by supplying air under pressure to appropriate rolls of the cylinders 16. The plate 15 is linked to the arms 26 and is swung down when the rolls are withdrawn. When a coil has been wound, the lower pinch roll 28 is shifted to direct the strip over rolls 34 to a further and similar coiling apparatus.

[Also in Group XL(b)] In order to avoid the shorted-turn effect in a waveguide Faraday rotator using high frequency field currents, the waveguide is longitudinally slotted and is surrounded by a material which offers a high impedance to currents generated by the field winding and a low impedance to the E.M. energy propagated in the guide. The material 23, Figs. 2, 7, fills the space between the waveguide 12 and the field winding 25 and also fills the slot 11. The ferrite element is in the usual form of a rod or rods 14, 14a supported by a dielectric filling 16. The material 23 may comprise an epoxy resin impregnated with particles of aluminium. Flanges 38, Fig. 5, on the ends of the waveguide may be provided with arcuate slots 32 which communicate with the longitudinal slot 33. The flanges are centrally recessed, the recess and the arcuate slots both being filled with semi-conductive material. The ends 37 of the waveguide may project into the recesses. The rotator shown in Fig. 7 comprises two H.F. field windings 25, 25a and a direct current winding 40 which is magnetically isolated from the windings 25, 25a by an elemental of high frequency magnetic core material.
